I'm getting the error in the picture attached when I try to read ecu.
Background:
I've tried 2 laptops and followed instructions exactly. I'm using a battery charger. I've tried this with the BMS tweaked version as well and I get the exact same error. The read process goes relatively quickly. It goes thru step 1 in just a few seconds and seems to skip to step 3 which only takes about 10 minutes then the error. I also don't get an estimated read time during the read...
Any ideas? I can't find where anyone else has had trouble with the read.
FYI--Protocol says "D-CAN"
Thanks!
